Telecom Technical Glossary

To effectively manage telecom cost optimization in Canada, one must first master the technical nomenclature used by Tier 1 providers. These terms form the basis of service level agreements (SLAs) and consumer contracts. Precision in terminology ensures that contract negotiations are based on verifiable technical performance rather than marketing abstractions.

Backhaul

The intermediate link between the core network (backbone) and the small subnetworks at the edge. In cellular networks, backhaul connects the cell site to the central office. High-capacity backhaul is critical for maintaining 5G speeds and reducing network congestion during peak hours.

Dark Fiber

Optical fiber infrastructure that has been installed but is not yet "lit" or utilized by active electronics. Enterprises often lease dark fiber to gain total control over their network equipment and latency, bypassing the standard commercial routing of internet service providers.

Latent Demand

A market condition where consumers would use more bandwidth if it were available or affordable. In the Canadian context, latent demand often exists in rural areas where infrastructure limits prevent the adoption of high-bandwidth digital content distribution services.

Over-Provisioning

The practice of allocating more bandwidth than is strictly necessary for a service to account for bursts in traffic. Most residential ISPs over-provision their lines by 10-20% to ensure that speed tests reflect the advertised rates despite protocol overhead.

• Bandwidth: The maximum rate of data transfer across a given path.
• Throughput: The actual amount of data successfully transferred over a period.
• Jitter: The variation in time between data packets arriving, caused by network congestion.
